LUBRlCATOR FOR VEHECLES.

SPECIFICATION forming part of Letters Patent No. 769,786, dated September 13, 1904. Application filed February 2, 1904. Serial No. 191,732. (No model.)

To all whom it may concern:

Be it known that I, HENRY B. BURDIOK, a citizen of the United States, residing at N ewkirk, in the county of Kay and Territory of Oklahoma, have invented a new and useful Lubricator for Vehicles, of which the following is a specification.

My invention relates to lubrieators, being especially designed for use in lubricating vehicle-axles, and has for its objects to produce a comparatively simple inexpensive device of this character which in practice will be sustained by the vehicle-axle and be wholly automatic in its operation of feeding lubricant to the axle-spindle.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a sectional elevation showing my improved lubricator applied for use. Fig. 2 is a section, on an enlarged scale, through the lubricator.

Referring to the drawings, 1 designates a vehicle-axle having a spindle 2, between the inner end of which and the axle there is provided a flange or shoulder 3, and 4 a hub having an inner boxing 5, provided at its rear end with a shoulder 6, designed in practice to thrust against the axle-shoulder 3. These parts are of the usual construction except that the flange 3 has provided therethrough at the top side of the axle an opening 7.

In the lubricator constituting the subject of this invention 8 designates an oil cup or reservoir carried by a branch tube or duct 9, which is in turn connected with a main discharge-duct 10 in the form of a tubular casing, having tapped into its normally upper end a plug or closure 11 and into its lower end a substantially conical discharge-nozzle 12, there being provided throughthe branch 9 an oil-passage 13, terminating at its lower end in an inlet-opening14, leading to the easing 10, whereby the oil may enter the latter. The flow of oil to the casing or duct 10 is regulated by a pin-valve 15, tapped through the branch 9, with its inner end adapted for movement into the passage 13, said valve being adjustable, as usual and as will be readily understood, for controlling the flow of oil through the passage.

Situated within thenozzle 12 is a longitudinally-movable primary valve-16 0f substantially conical form and'terminating at its outlet end in a pin or extension 17, designed to project through the lower open end of the nozzle and extend a suitable distance beyond the latter. The valve or closure 16 is carried at the lower end of a longitudinally-movable rod or plunger 18, which carries between its ends and at a point suitably remote from the inner end of the valve 16 a secondary valve or closure 19,v threaded onto the plunger-rod 18 for adjustment longitudinally of the latter, or, in other words, toward and from the primary valve 16. The valve 19, which in practice is designed to alternately open or close the passage 13 by traveling back and forth over the opening 14, is peripherally grooved for the reception of suitable packing 20 and is further perforated by a series of oil openings or passages 21, through which the oil may flow to the space 22 between the valves.

The valve 16 is pressed to its seat and in normally closed position by means of a spring 23, disposed between the plug 11 and valve 19, it being apparent that the tension of this spring may be regulated for varying the force required to open the valve 16 by adjusting either the plug or valve 19, or both, and, further, that the valve 19 maybe adjusted along the rod 18 to accord with the amount of movement which the valve 16 is to have, it being understood, of course, that it is the intention for valve 19 to close the passage 13 whenever the valve 16 moves to open position.

The lubricator is sustained in position on the axle by means of a clip or bracket 24:, which detachably engages the axle and embraces the casing or duct 10. When the lubricator is in operative position upon the axle, the pin or extension 17 will project through theopening 7 in position for its outer end to be struck by the shoulder 6 during the end thrust of the hub 4.

In practice as the wheel revolves upon the spindle 2 the end thrust of the hub will serve to force the valve 16 inward against the acthe passage 13 and openings 21 for aocumulation in the space 22, this flow of the oil being, however, regulated by means of the pin-valve 15 in the manner heretofore explained.

From the foregoing it will be seen that I produce a simple inexpensive device which is admirably adapted for the attainment of the ends in view; but it is to be understood that I do not limit myself to the precise details herein set forth, inasmuch as minor changes may be made therein without departing from the spirit of the invention.

Having thus described the invention, what 'is claimed is 1. In a lubricator, the combination with a tubular casing having discharge and inlet ports, of an adjustable closure tapped into one end of the casing, an oil-reservoir communieating with the latter, a valve-stem movable longitudinally of the casing and carrying primary and secondary valves adapted respectively for alternately closing said ports, said valves being relatively adjustable on the stem,

and a spring disposed in the casing between the closure and secondary valve, and acting to maintain the primary valve normally in closed position, said closure being operable for varying the tension of the spring.

2. In a lubricator, the combination with a tubular casing having inlet and discharge ports, of an oil-reservoir communicating with the casing, a valve-stem movable within the casing, a primary valve carried by the stem for closing the discharge-port, a secondary valve threaded on the stem for closing the inlet-port, said secondary valve being spaced from the primary valve and having oil-passages therethrough leading to said space, and

means for maintaining the valves in normal position with the discharge-port closed.

3. In a lubricator, the combination with a tubular casing having an inlet-port and a discharge-nozzle, of an oil-reservoir communicating with the casing, a primary valve within the casing for normally closing the dischargenozzle and having a pin or extension projecting outward through the latter, a secondary valve operatively connected with the primary valve for closing the inlet-port, and means for maintaining the valve in normal position.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

HENRY B. BURDICK.
